onsemi NCP1096PAR2G

The NCP1096 is a member of the Power over Ethernet Powered Device (PoE−PD) product family, and allows the device containing the NCP1096 based PD to become an IEEE 802.3af/at and −3bt compliant powered equipment. It incorporates all the required functions for operation within a PoE system such as detection, classification and current limiting during the inrush phase. The NCP1096 supports high-power applications (up to 90 W PoE) through an internal pass transistor. A power good pin guarantees proper disabling/enabling of the adjacent main DC/DC converter. The classification result pins allow for operation according to the assigned power Class (up to Class 8). The NCP1096 also offers Autoclass support and indicates when a short Maintain Power Signature can be implemented. In addition an auxiliary supply detection pin allows NCP1096 to be used in applications where power can be supplied by either PoE or by a wall adapter.
